This standard specifies the method for determining the breaking strength of bitumen-based waterproofing and damp-proofing felts. It details the required apparatus, test specimen preparation, conditioning, test procedure, and calculation for both longitudinal and transverse directions.
Bitumen-based felts - Method of the test, Part 1: Breaking strength test
Quick Reference Values
Sample drying temperature105 ± 5 °C
Test specimen area100 cm²
Analytical balance accuracy0.001 g
Key Formulas
Binder Content, % by mass = ((M1 - M2) / M1) * 100
Practical Notes
This is a destructive test primarily used for quality control by manufacturers and for third-party verification.
Ensure adequate ventilation and use appropriate personal protective equipment (PPE) when handling solvents like trichloroethylene.
The accuracy of the result is highly dependent on drying the sample to a constant mass before and after extraction.
